it looks like maybe the gif is sped up until the accident, considering it's stutter-y look and how quickly he braked. I'm not positive but I think the red car pulled into their lane, forcing them to go to the left most lane where the pedestrian was standing

I've always imagined that I would jump like this if a car was about to hit me. Good to get some validation that it can actually work. I mean, this guy could've died or ended up with serious injuries if he didn't.

A smart move to jump up but don't think he just walked away after that. There is a chance that the fractured something around his hip. He might seem fine because he is standing up in the end but the adrenaline makes him feel no pain. Smartest thing he could do in the situation (except for jumping out of the way if he had the time) but just saying it's not like in the movies.

I don't have a license so take it with a grain of salt, but as I understand, it's mostly just to have a proof in case of an accident. Regular crashes, minor accidents, cops framing you for something. Dashcams are cheap and extremely helpful, why not to have one?

I agree he is coming up toward the car (just to the left of the white van. then he seems to stop next the van for a second then walks closer to the moving car. He jumps about 3-4 meters between frames 39-40
